  • Background: Despite recent valuable steps in initiating a cancer registry in Iran, data depicting prevalence, incidence, and clinical picture of pancreatic tumors in the country are exceedinglyly sparse. With the aim of filling this knowledge gap, we reviewed cases in the pathology archive of Shahid Sadoughi hospital (Yazd, Iran), between 2001 and 2011. Materials and Methods: Medical records of 177 patients are reported in the present study. In cases for which paraffin-embedded blocks were available, the specimens were evaluated by two independent pathologists blinded to the primary diagnosis. We extrapolated the frequency of malignant lesions in our study to the population of Yazd province, derived from national census data, to generate cancer incidence rates. Results: Final diagnosis of malignancy was made in 117 cases (66.1%), and the remainder (60 lesions, 33.9%) were classified as benign. Adenecarcinoma and neuroendocrine tumors were the two most common histological types of malignancy identified in 88 (75.2%) and 11 (9.4%) specimens, respectively. Crude annual incidence of pancreatic cancer was 0.55 per 100,000 person in 2001 and increased to 1.68 in 2011. Age standardized incidence rates in 2001 and 2011 were 0.75 and 2.68, respectively. A significant increasing trend in cancer incidence was observed during the 11 years of the study period (r=+0.856, p=0.009). Sex-stratified analysis, confirmed the observed trend in men (r=+0.728, p=0.034), but not women (r=+0.635, p=0.083). Conclusions: Over the past decade, incidence of pancreas malignancies has risen steadily in Yazd, Iran. Nevertheless, these figures are still substantially lower than those prevalent in developed nations.

  • Objectives: The purpose of this study was to investigate the environmental pollution caused by exposure to air pollution in Korea. Therefore, it is necessary to investigate environmental and health factors through big data. Methods: Among the environmental diseases, the data centered on "percentage per day in 2015 to 2018". Data of environmental diseases and concentrations of air pollution monitoring network were analyzed. Results: Lung cancer and bronchiolitis obliterans were correlated with 0.027 and 0.0158, respectively, in the contamination concentration of fine dust ($PM_{10}$). Ozone, COPD, allergic rhinitis, and bronchiolitis obliterans were correlated with 0.0022, 0.0028 and 0.0093, respectively. At the concentration of $SO_2$ and the diseases of asthma, atopic dermatitis, lung cancer and bronchiolitis obliterans were 0.0008, 0.0523, 0.0016 and 0.0126, respectively. Conclusions: We surveyed the trends of air pollution according to the characteristics of Seoul area in Korea and evaluated the perception of Korea and the world. As a result, respiratory lung disease is thought to be a major factor in exposure to environmental pollution.

  • Currently, the prevalence of gastroesophageal junction adenocarcinoma (GEJAC) is increasing in both Asian and Western countries, although the increasing rate in Asian countries is much slower than in Western countries. With these current trends, concerns regarding the surgical treatment method are also increasing among gastrointestinal surgeons. However, the surgical treatment for GEJAC has been a controversial issue for a long time due to the relative scarcity of this tumor and its characteristics from its borderline location. Recently, a large-scale prospective study of this tumor has been conducted in Japan, and the results are now available. The results of this study will be helpful for understanding this tumor. In this article, the pattern of lymph node metastasis of GEJAC is reviewed, and the extent and method of lymph node dissection for this tumor are discussed and proposed based on the review.

  • One of the interesting trends in genome research is the study about epigenetic modification above single gene level. Epigenetics refers study about heritable change in the genome, which accompany modification in DNA or Chromatin besides DNA sequence alteration. We used to have the idea that the coding potential of the genome lies within the arrangement of the four bases A, T, G, C; However, additional information that affects phenotype is stored in the distribution of the modified base 5-methylcytosine. This form of information storage is flexible enough to be adapted for different somatic cell types, yet is stable enough to be retained during mitosis and/or meiosis. Epigenetic modification is a modification of the genome, as opposed to being part of the genome, so is known as "epigenetics"(Greek for "upon" genetics). This modification could be methylation on Cytosine base or post translational modification on histone protein(methylation, acetylation, phosphorylation, Sumoylation)($Dimitrijevi\hat{E}$ et al 2005). In this review, we would like to focus on the relationship of DNA methylation and cancer.

  • Background: Findings of epidemiologic studies on the relationship between fruit and vegetable consumption and prostate cancer (PCa) risk have been inconclusive. We therefore examined the association between intake of fruits and vegetables and PCa risk in Iran. Materials and Methods: In this hospital based, case-control study, a total of 50 patients with PCa and 100 controls underwent face-to-face interviews. Regression analysis was used to examine the relation between fruit and vegetable intake and PCa risk. Results: A protective independent effect was observed for the highest tertile of total fruit and vegetable (OR: 0.33, CI: 0.04-0.30, p value<0.001), total fruit (OR: 0.30, CI: 0.06-0.4, p value=0.03) and total vegetable (OR: 0.31, CI: 0.02-0.21, p value<0.001) consumption. Within the group of fruits, a significant inverse association was observed for apple and pomegranate (p trends were 0.01 and 0.016, respectively). In the vegetable group, a significant inverse association was observed for tomatoes (p trend<0.001) and cabbage (p trend=0.021). Conclusions: The results of the present study suggested that fruits and vegetable intake might be negatively associated with PCa risk.

  • Nasopharyngeal carcinoma (NPC) is an uncommon disease in most countries but occurs with much greater frequency in southern China. This study aimed to examine the secular trends of NPC in urban Guangzhou over the time period of 2000-2011 using data from the Guangzhou Cancer Registry. Age-adjusted annual incidence rates of NPC were calculated by the direct method using the WHO World Standard Population (1960) as the reference. The average annual percentage change (AAPC) was used as an estimate of the trend. A total of 7,532 new cases of NPC and 3,449 related deaths were registered. In both genders, the peak incidence occurred in the 50- to 59-year age group, and this age distribution pattern remained similar throughout. The AAPC in NPC incidence rates was -3.26% (95% CI: -5.4%--1.1) for males and -5.74% (95% CI: -8.9%--2.5) for females, resulting in a total decrease of 39.3% (from 22.14 to 13.44 per 100,000 population) for males and 48.6% (from 10.1 to 5.18 per 100,000 population) for females over this 12-year period. The AAPCs in NPC mortality rates were -4.62% (95%CI: -3.5%--5.7) for males and -6.75% (95% CI: -5.2%--8.3) for females, resulting in a total decrease of -46.1% (from 12.1 to 6.54 per 100,000 population) for males and 51.7% (from 4.14 to 2.00 per 100,000 population) for females. The age-adjusted incidence and mortality rates of NPC declined during 2000-2011 in urban Guangzhou but remained high. Future efforts to improve prevention, early detection and treatment strategies are needed.

  • Purpose: This study was attempted to see the trends in breast cancer researches in Korea. Method: We collected a total of 94 articles associated with breast cancer and published in Korea from 1976 to August 2004 and analyzed the characteristics of those articles, the journals which published those articles in each year, the research designs, subjects, intervention effects in experimental studies, the subjects and concept distribution in comparative researches and themes of the articles. Result: 1. Articles published and associated with breast cancer have increased since 1990 and picked after 2000. 2. Most research designs are survey and correlation studies which are non-experimental research(70.2%) and next are experimental and qualitative researches. 3. In a total 17 articles which are experimental researches, intervention studies which use exercise programs are most(5 articles) and the next are education program, supportive nursing intervention, guided imagery, massage and rehabilitation programs. 4. In correlational researches, concepts such like social-psychological adaptation, partner support, health promotion behavior and family support are treated frequently. 5. Subjects in most comparative studies are patients with breast cancer and normal women. 6. Most nursing research themes are psycho/spiritual problems, 16 articles(17.0%). Conclusion: These results show that the researches related with breast cancer have actively increased and body functions and psycho-social variables have been improved through nursing intervention. Therefore, it seems that more systematic interdisciplinary studies and systematic complement are necessary for future breast cancer nursing researches.

  • Background: Although the prevalence of cancer is increasing, it is no longer synonymous with death. The number of cancer survivors is estimated to be increasing due to development in medical treatments and social programs; cancer survivors are increasingly returning to work after long-term unemployment. Thus, we examined the quality of life (QOL) and the factors associated with return of cancer survivors to the workplace. Materials and Methods: This study was performed using the 2008 Community Health Survey administered by the Korea Centers for Disease Control and Prevention (N=548). We used Chi-square tests to compare demographic variables based on self-perceived health status, and analysis of variance (ANOVA) to compare QOL scores among groups. We also performed a mixed-model analysis of the relationship between QOL and factors at the workplaces of cancer survivors. Results: Based on the results of our study, the overall QOL of cancer survivors was associated with 'mutual respect', 'free emotional expression', occupation, and age. Moreover, different trends of QOL according to self-perceived health were identified on additional analysis. In the 'bad' self-perceived health group, QOL was significantly different according to income. The QOL of cancer survivors in the low-income group was lower than in the other groups. Conversely, the 'normal' group had a lower QOL caused by 'no mutual respect' and "no free emotional expression" in the workplace. The QOL in the 'good' group based on self-perceived health was higher in the younger age group. Conclusions: There may be a significant relationship between QOL and workplace factors for cancer survivors, although further study is needed to investigate this relationship in detail. This may facilitate formulation of policy and efforts to prevent and manage the decline in the QOL of cancer survivors returning to work.
